Filed: 1967-01-11
Abstract: 1,144,283. Power hammers. MAGDEBURGER ARMATURENWERKE, " KARL MARX ". 11 Jan., 1967, No. 1462/67. Addition to 1,136,172. Heading B3H. A high speed hammer comprises a housing 1 containing a first chamber 6 supplied with pressurized fluid, a first piston 10 reciprocable in the chamber and having an enlarged free end 10c adapted to be received with sealing engagement in a second chamber 16 connected through a spring-loaded valve 18 with a third chamber 2c in open communication through ports 2b with the first chamber 6, and a cylinder 14 containing a second, piston 13 connected by a hollow rod 11 with fluid discharge apertures 11c, to a stop nut 11a disposed in a bore 10a of the first piston and adapted to engage a stop screw 10b thereof so as to raise the first piston when pressure fluid is admitted through port 15a below the second piston. During its upward movement the free end 10c of piston 10 passes through a seal 21 into chamber 16. The chambers 2c, 6 are then charged with pressure fluid through conduit 15b thereby closing valve 18. To initiate the working stroke of piston 10 pressure fluid is admitted, preferably automatically, through port 14a which lowers piston 13 and opens valve 18. This moves piston end 10c out of chamber 16 by differential pressure whereupon the piston 10 is accelerated suddenly to produce the blow. A disc 22 co-operates with the end 10c to cushion the end of the working stroke.

Title: Depth bombs
IPC: F42C14/04
Filed: 1927-01-18
Abstract: 265,570. Dieter, W. F'eb. 3, 1926, [Convention date]. Projectile fuzes.-Relates to depth bombs controlled by hydrostats one of which at a certain depth positions the parts so that the charge can be fired by the detonator when exploded by the second hydrostat at a greater depth. According to the invention, safety means comprising a sliding member normally cuts off communication between the detonator and the charge and is moved by a hydrostat to establish communication at a given depth so that the detonator, when released at a greater depth by another hydrostat and exploded, can fire the charge. As shown, a sliding member J in a transverse sleeve H normally covers a firing hole p communicating with a primary charge C arranged within the main charge B, and at a given depth is moved against a spring b to align an aperture r with the hole p by the pressure of the water acting on a diaphragm a. An internal lug on a fixed ring s engages a longitudinal groove in the member J to prevent it from turning. This movement carries a piston i on the member J out of the part g of the slide H so that water can pass through the apertured cap j and a passage T to advance a spring-pressed piston L in a cylinder M, whereby a cartridge D, carried by a cylinder N from the piston L, and guided in a frangible disc t' in a ring t, is protruded into a chamber q in the primary charge. A firing pin P<1> is carried by a spring-pressed plunger P in the cylinder N and normally locked by sears R, but at a predetermined depth, the pressure on the piston I. is sufficient to force the sears against the ring t so that they disengage the firing pin which then explodes the cartridge, whereby first the primary charge C and then the main charge B are fired. The primary charge C may be dispensed with. The safety slide ensures that premature explosion of a cartridge shall not fire the main charge and provides for escaping gases from such explosion passing away through the hollow part w and merely blowing out a cap x which serves to prevent entrance of water and also as an indicator that the cartridge is intact. The protrusion of the member J through the side of the main shell A, when not correctly set in safety position, also constitutes an indicator and precludes its insertion in a torpedo discharging tube when used for launching the bomb. Vents y<1>, z prevent back-pressure on the hydrostats by communicating with a large chamber U in the bomb.

Title: Apparatus for the transmission of views, scenes or images to a distance
IPC: H04N3/02
Filed: 1926-01-20
Abstract: 269,658. Baird, J. L., and Television, Ltd. Jan. 20, 1926. Television.-To obtain the advantages of a very high intensity of light acting on the light sensitive cell at the transmitting station, the object of which an image is to be transmitted is illuminated by traversing over it a spot of light of an intensity such as would be injurious to the object if directed continuously on to any one part thereof. Fig. 2 shows one arrangement in which the usual exploring device comprising a spiral series of lenses 18 on a rotary disc 16, as described in Specification 230,576, is used to traverse the spot of light from the source 17 over the object 14 and to project the light reflected from the elemental areas of the object thus successively illuminated on to the cell 15. In a modification, Fig. 3, the light from a source 23 is reflected on to the object 21 by a spiral series of mirrors 20 on the disc. The light source in each case is shielded to prevent its direct illumination of the cell. Alternatively the traversing by the spot of light may be effected by directing a beam from the source through two refracting prisms at right angles and subjecting these to mechanical movements about axes parallel to the edges of their refracting angles. Or prisms similarly arranged and comprising vessels filled with nitrobenzene or like liquid may be subjected to electrostatic or electromagnetic stresses for varying their refracting properties. The traversing movement in one direction may be effected by lenses or mirrors and m the other direction by a prism operated or controlled as above. The invention is applicable to a system employing a block of light-sensitive cells on which an image of the object is projected. According to the Provisional Specification the traversing by the spot of light may be effected by a slotted shutter or by various rotating or reciprocating arrangement of lenses or mirrors.

Title: Horizontal deflection circuits
IPC: H03K4/62
Filed: 1972-01-13
Abstract: 1338754 EHT supplies SONY CORP 13 Jan 1972 [29 Jan 1971 6 Nov 1971] 1706/72 Heading H2F [Also in Division H3] A combined line time-base and EHT generator circuit comprises a gate turn-off rectifier 18 driving the deflection coils 14 and a semiconductor switch, e.g. gate controlled rectifier 7, driving the EHT transformer 5, a pair of diodes 21, 22 being connected in series with the switch and the junction between the rectifiers being connected to the gate of rectifier 18. In operation, a pulse from transformer 2 turns on 7 and the output current flows through diode 21 and divides between the gate of 18 and diode 22. 18 therefore switches on producing a rising current in the deflection coils and thus the second half of the scan. The current from 7 charges a capacitor 27, directing more of the rising current from 7 to the diode 22. When the pulse from transformer 2 reverses it produces a reverse switch-off current through the gate cathode peak of 7 and diodes 21 and 22 and this continues until the diodes are discharged. 22 discharges first so that the reverse current is then switched to the gate of 18 to switch it off. The switch-off of 7 produces an E.H.T. pulse in the secondary of a transformer 5 and the switch-off of 18 allows the first-half of the scan to be produced in conventional manner through diode 16. In Figs. 3 and 6 (notshown) the E.H.T. gate turnoff switch 7 is replaced, a transistor (31) and a by-pass path is provided between the emitter and base of the transistor for the remaining gate switch-off current. In Figs. 1 and 3 (not shown) a separate transformer winding is provided in series with 26, 27 to control gate turn-off switch 18. Fig. 1, also includes positive feedback from a capacitor 15 in series with the deflection coils to raise the gate voltage at the time of switch-on and lower it at switch-off.

Abstract: 638,153. Manually-actuated piston valves. COLLINS, J. E., and MORTON, C. K. Jan. 20, 1947, No. 1800. [Class 135] [Also in Group XXVI] A fluid valve comprises a reciprocating plunger 12 extending through a bore in a tubular body 10 and supported by end abutment caps 13 so as to form an annular chamber 35 between the plunger and the body which is divided by an annular abutment ring 44 into supply and discharge compartments connected respectively with supply and discharge ports 25, 26. A spring 45 presses sealing rings 37, 38 against one end abutment cap and against the annular abutment ring respectively, while a perforated tubular extension of the abutment ring presses a sealing ring 36 against the other abutment cap. The sealing rings are U-shaped, seat away from the supply port, and have bevelled spreader rings 39, 40, 41 urging the sealing rings into contact with the plunger. A reduced portion 33 on the plunger allows fluid to flow from the supply to the discharge port in one end position of the plunger, or from the discharge to an exhaust port 14 in the other end position of the plunger as shown. In another embodiment, two pairs of sealing rings on either side of two annular abutment rings are pressed apart by a central spring so that a plunger having two reduced portions allows fluid to flow from a supply port to either one of two discharge ports, the other discharge port being opened to one of two exhaust ports formed at the ends of the bore. In a further modification, the reduced portion on the plunger is replaced by longitudinal grooves.

[Also in Groups XXVI and XXVIII] The delivery of a constant stroke fluid pump is controlled by variably regulating the fluid pressure differential established across the check valves 28 controlling the pump discharge ports 33 so as to vary the period of time the check valves are seated during the suction-stroke of the pump. Fig. 1 shows a swash-plate pump 10 for supplying liquid fuel to the burners of a gas turbine or jet propulsion engine past a throttle or control device 58. The pump 10 (see Group XXVIII) comprises a swash-plate 471 driven from the engine through a shaft 48 and adapted to reciprocate pump plungers 18 in pumping chambers 23 having inlet ports 24 and discharge ports 33. The fuel passing the valves 28 flows through ports 34<SP>1</SP>, 36 to a common chamber 37 connected to the pump delivery pipe 39. The valves 28 are loaded in the closing direction by springs 41 and the chambers 40 at the rear of the valves communicate with the pump delivery pressure by restricted orifices 42 in the valves themselves or by a bleed between the chamber 37 and an annular manifold 44 connected to the chambers 40 by ports 43. The manifold 44 is connected by conduit 45 to a regulating device comprising a valve 60 actuated by a spring-loaded diaphragm 61 subject to the pressure drop across the throttle 58. The valve 60 is adapted to connect the conduit 45 to the low-pressure side of the pump through a further conduit 71. The pressure drop across the valve 60 is regulated by a further valve 72 actuated by a spring-loaded diaphragm 73 and having ports 70 in a hollow sliding valve member. The passage 45 is connected to a chamber 74 on one side of the diaphragm 73 by a passage 75 with a calibrated restriction 75<SP>1</SP>. This arrangement limits the rate of response of the valve 72 and serves to prevent surges in the main delivery pipe 39.
